1917. Serial No. 177,778.

To all whom 'it may concern.' Be it known that 1,-JOHN H. GILMAN, a citizen ofthe United States, anda resident of Ottawa, in the county4 of LaSalle, and State oflllinos, have invented certain new and useful Improvements in Elevators for Corn, &c., of which the following is a full, clear, and exactspecifieation. l

My invention is concerned with elevators of the vertical type which are adapted tobe placed in the center of narrow driveways, which necessitate the lower portion being hinged so that it can be swung up out of .the way to permit a wagon to pass-beneath itto get, into dumping position, and vwhich Iare provided with p1voted'hoppers widened ,at their outer ends to encompass the end of the `wagon bed, the contents` of which are `being elevated, and4 narrowed at their-inner pivoted ends to "discharge into the narrower elevator b oot, said hoppers being adapted to be oldedfup parallel to the. hinged portion of the` elevator-casing while the latter is swu up'out "of the wayand vto be springheld 1n4 contact with-the rear end of' the under side of the wagon-bed while it is in use, despite the rise andfall'of the latter as it sfbein dumped, orthe variation inthe height o diiferent rwagon-beds above the ground, and iS embqdffn Slih an .elevator m which the contented ,the hopper.. will be fed steadily tothe Ve1arat -r.d,jsiglae"chevarying angles assumed by said hopperfhand' the contraction in the cenacityhereot.ofthe inner-, Qy discharge end as compared with the Quer winnend: -il t Thepresent application is a,d,ivision.of my` original appllcation No. 871,646, filed December 17,71914,4and to illustrate'mil invention, I` haveannexedhereto two ,s eets I of.) drawings, in which the .s amefreference cliaractersare used to desi'nate identical .Parts 0f all thef uws of w ichs.4

e 'rear endvf plied tre to, and showing ft an enlar ed scale, as

secion on the line hand side of Fig. 1, but also on anenlarged scale; and

Figs. 5 and 6 are details in section on the Elevators of the type herein shown contain a vertical stationary portion 10 of the conveyer trough or framework, to which is pivoted at 11 the lower 4portion 12 of the same framework, which is adapted to be lines B-B and C-C of Fig. 2, but also on an enlarged scale.

swung and' lifted by ,the chain 13 secured to the lower end thereof, from the vertical operative position shown in full lines in Fig. l to the horizontal inoperative `position ini vdicated in dotted lines, to permit a wagon to drive beneath the elevator and into the dumplng position shown. When the'wagon has been driven into dumping position, the

Alower section `l2 of the framework or troufrh is swung down from itsl dotted-line to its rfull-line"position, the hopper 14 having been previously swung down so that it will counterbalaneed by Sonie g's'uitab e mecha- `that `it canjbefsw'fmg .up without any diiiculty,`itbecomesf yadvisable to lock said sec,- tion in its operative position, for which purpose 1 'maly employ the previously i mentioned locking lever 16, whlch has any` Vsuitable connections for holdingthe portion 12 againstswinging while it is in use.

Inthese elevators, a series of cups 37, are

suspended between the pairs ofv sprocket chains4 .36,-` which chains, coopera-te4 ,with

'sprocket wheels y39 sef'zu'red` on the shaft 40 journaled .in th`e` I of., the lower section 12. The chains-BSaredriven'by any suitable power, so that in operation the cups are carried up, colltlllcglsly'to liftlthe, grain to the top [of the elevator.; ju:S.uitallfilei: .spring connections, are "employed between;l the Swinging portion ,A12 of ,thsonryar frame and; the .hop er 14, Such tor instance with tanguy-co1 ad @brin-mir spion# as cny nected at their flower 'ends to thebars 33fse cured to'thesidesof the hopper, while their upper ends are secured to the lower ends of the chains-34, the upper endsvof which-are secured at 35 to theveasing 12. The ltrough or casing 12 has in the lower side thereof, adjacent the hopper 14, the opening 41 formed 'by omitting a portion of the wall,"

and thesbottom ofthe casing takes the form of a bootl 42, preferably formed of heavy sheet-metal cut and bent into the shape shown. The end 43 of said sheet-metal is utilized to form the fixed member of a hinge 44, the other member 45 of which is' bolted to the board 46 forming the supportforithe lower end of the hopper 14. This board 46 has bolted thereto the two side pieces 47, which are preferably of the shape clearly shown in Fig. 2, and form the bottom of the hopper except so far as the same is formed -by the reciprocating feeding member 4S. 'Ehe upper surface of this reciprocating feeding member is provided with the ratchet bars 49, the teeth of which face downwardly, and it is adapted to reciprocate on bearings formed at its lower end by the upper surface of the bar 46 and the opposed,4 plates 50, as'seen .in Figs. 2 and 3, and held in place by the bolts 51, while the bearings at the upper end are formed by the o pposedplates 52- and 50 secured at the top and bottom offthe edges ofthe piece 4 7`by the boltsfl. The bottom of thehopper :is strengthened at'the outerendl bythe crossfpiece's; 55 and 56 eX- tending acrosssai'dend and suitably secured Atoithe' pieces 47. The 'sides of the hopper, whichfc'onverge as seen in Eig. 2,` may be formed of sheet-metal, or in any manner desired, and they are designed to hold the corn onfhe lbottom ofthe hopper and direct itinto the ToI'eciprocate-the feeding member 48V-'il mount loosely o'nthe outer end of :the shaft 4Q, which is Irotated by conveying mechanism, thesprocket wheel VK58;, and I spline on theouter off this shaft 40 the clutch sleeve 59iyvhich is 'moved bythe clutch lever- 60, fulcr,umed to the wallof the lower section at 61, into and out of engagement with the clutch member 62 formed' on thehopper of 'the sprocket wheel 5S. A. SPLEQC- kt chain 63 connectsthis sprocket wheel 58 with a sprocketv fwhee164 secured on the outer end off the shaft 65 journaled in ,bearings 66 formed c 'n Athe bracket 67 secured" tothe the bottom end# at .present consider` best i Out itapulrposi-ss, 4 it A'will be understood that 115 vmay',be:necessi;grad by thefsmte 'of the p rigr williibe Teciprccaited' andl the teeth 49 will force the-corn down into the boot so that it will be positively forced into the cups 37 to be. carried up thereby to the top-ofthe elevator.

When the elevator is not in use, the hopper: A14 :is swung up and secured with its botto-m against the adjacent side ofthe elewith the widely separated ends of itsI Sides cooperating with the sides of the end of the wagon'bed, against the bottom of which the hopper is held by the .action of the springs 32. With the. elevator run-ning, the free end of the wagon-bed .is gradually lifted lby any of the well-known wagondumps', lowering the rear end slightly and further depressing the hopper 14, which engages the under side of said rear end. As 'the wagon-bed is tilted more and more, with ateremoved, the corn flows in a. stream, w ichiis apt tol be veryjunsteady, intothe hopper 14, and if it is ear corn, the hopper, without the reciprocating feed mechanlsm shown, unless inclined more than is practicable w'theut digging afrit t0 receive the1,boot42,is sure to clog np', 'owing to the necessary contraction of thepassageway resulting Iffro'm the narrowing of the 'hopper .frein v#he Width ,0f the Wagenfbed tothatof the elevator-casing. The vreciprocation ofk the serrated bottom 'portonl'-48 through this rnarrowed throat @serves to break up the jam, and'keeps the,V device feeding. steadily and. satisfactorily without any attention ,fromtheidriver until contents of the wagon are completely discharged and elevated-1 c 4VVhile I hayeshown and .described iinv'ention as einibodied in! the form` which vI adapted to ll'y it is capable qffsome modification, that I d0 notidesre .to belimited' .i11the inter prestation of the following claims lexcept art What ,I'clm as new, and desiretorseeure the United, Snes, is: 1- Inlan-e1t9riorcerm etcathacembi'- nation with anarrow elevatorfscasingmf; an
